  • I’ve been running my own email server for 15+ years. One year ago I needed to change VPS providers and thus get a totally different IP. I worried about this a bit, but actually had no issues whatsoever. Of course, I wasn’t starting completely from scratch as I had the same domain, all my personal experience, and a battle-tested configuration for docker-mailserver. But yeah, the lack of IP reremovedtion itself didn’t seem to be an issue at all. Maybe I got lucky. Or maybe it’s because I chose a relatively small Canadian VPS provider rather than one of the global cloud giants (I assume their IP address space gets pretty trashed with scammers).



  • All MTAs have retries baked in, so running a self-hosted email server that receives mail is actually one of the most forgiving services in this respect. If your server is offline, the sending server will retry several times over 24-48 hours before it gives up. Even the big cloud email providers will do this.

    That said, there are other aspects of running an email server that require some extra rigour, but they’re more on the sending side (making sure emails you send to other people actually land in their inbox). Doable, but one of the more challenging things to self-host.






  • for personal use

    A key part of his argument is that these laws should be repealed so that small companies could legally develop hacks and alternatives. For example a startup could develop (and support) an alternative firmware for John Deere tractors, which they sell to independent tractor repair shops around the world, creating more competition, more options, and cheaper/better services to end users. The “for personal use” version of that is fine for us hobbyists, but prevents similar freedoms from being accessible to regular people.

    What if you rent a bare metal server in a data center? Or rent a VPS from a basic provider that expects you to do your own firewalling? Or run your home lab docker host on the same vlan as other less trusted hosts?

    It would be nice if there was a reliable way to run a firewall on the same host that’s running docker.

    You may say these are obscure use cases and that they are Wrong and Bad. Maybe you’re right, but personally I think it’s an unfortunate gap in expected functionality, if for no other reason than defense-in-depth.
